In the process of cleaning up some stuff, I joined several DBs into one DB. They all where using the default prefix of "wp_". I did an export and renamed the prefix to something different (let's say "new_"). I just renamed the tables and NOT the data in the tables. After I imported the data, I changed the information in the wp-config.php file.
The site works, but I can't get into create new posts or do anything. Where did I mess up and how can I fix it?
